The D8S combines everything you can want
for top-level buggy racing into one convenient package - just add
fuel and batteries and get on the track! With the World
Championship-winning heritage behind the HB D8 combined with the
ready to run flexibility of HPI radio gear and the bulletproof
Nitro Star F3.5 engine, you can easily get the best of both worlds
as soon as you open the box. Race-proven by World Champions and
backed by HPI, you can't go wrong with the HPI D8S. Because the D8S
chassis and suspension parts are exactly the same as the HB D8, the
D8S is ready to upgrade with Atsushi Hara Edition parts from
HB!

frequencies or radio conflicts. The radio features a pistol-grip
design with steering wheel for ease of use and realistic
control, compact size, servo reversing and a light
weight due to it requiring only four AA batteries.With the
adjustable, built-in failsafe feature, you will be protected in

World Champion Design

The D8S is a 'race roller' version of the HB
D8, making it the perfect way to jump into nitro buggy racing! With
the design and capability of the World Champion D8 as its
foundation, the D8S is your introduction to race-winning
glory!

Powerful F3.5 Racing Engine

Driving the D8S forward is the F3.5 engine,
which has been an extra-strong engine fitted in Savage monster
truck and Trophy buggy kits for many years. The F3.5 is equipped
with a pullstarter for easy starting without an expensive starter
box, and it can also be started using a starter box for twice the
convenience. For maximum power, the F3.5 is fitted with an
aluminium tuned pipe for plenty of wheel-spinning torque off the
line and loads of top speed at full RPM!

Race-Ready Electronics

The D8S is fully equipped and ready to race.
With the 2.4GHz radio, you can adjust everything you'd expect on
more expensive computer radios. The SB-5 steering servo is
extra-powerful to handling full-throttle race conditions, which
means it can handle the punishment of steering the wheels at full
speed, the ultimate test of a servo's strength.

Easy to Remove Radio Tray

Aiding clean-up of the chassis at the end of
the race day is the easily removable radio tray, just a few screws
takes all the electronics out of the chassis to keep fluids and
water away from expensive servos, receiver, etc. We know racers
like to get dirty, but a clean car is a happy car! (Note: Servos
shown in picture are for illustrative purposes only.)

HB Composite Chassis Braces

Strong composite chassis braces connect the
front and rear bulkheads to the middle of the chassis for extra
rigidity. Special composite material is used for extreme light
weight, helping to enhance the driving feel, acceleration and
braking of the car.

Championship Suspension

With the race-winning suspension design and
features of the D8 on board, you will experience a pure driving
feel and total adjustability like never before! Tune the D8S to
your driving style and track conditions with the aid of the full
range of adjustments: shock position, oil, springs, roll centre,
wheelbase, camber, sway bars and more! the front suspension
features a long list of features, including the HB Inverse Steering
Block Design, adjustable roll centre, thick turnbuckle links,
aligned king pin and universal joint pivots, sway bar, steel
turnbuckles and HB's own counter-rotating shock mount screws.

The D8 solid suspension arms prevent mud
build-up and also stop rocks from binding the suspension. The exact
compound of composite material used is a Team HB secret, and was
developed over months of testing in wet and dry racing conditions.
Each suspension arm also features handy travel-limiting droop
screws to allow you extra tuning ability when you're up against the
clock and the competition.

Point-and-Shoot Steering

The D8S steering system uses thick anodized
aluminium steering bar and thick steel turnbuckles to guide you
through the pack during a race. Steel screws, locking nuts and
sturdy nylon steering arms and turnbuckle links complete the
steering. A hand-adjustable servo saver provides extra peace of
mind for your steering servo, and four sealed ball bearings let the
steering glide effortlessly in the muckiest of conditions.

HB D8 Big Bore Shocks

The HB Big Bore shocks are MASSIVE - at 16mm
across, they are among the biggest shocks you can find on any
racing kit. With rubber boots, hard-anodized bodies and threaded
adjustments, they have all the standard features you'd expect from
any top-level competition kit.

High Efficiency Shaft 4WD Drivetrain

The D8S is equipped with the World Champion
drivetrain straight out of the D8 buggy - three oil-filled gear
diffs with spiral-cut gears, full-time shaft 4WD drivetrain
supported by rubber-sealed ball bearings, high-strength steel
driveshafts and axles and much more!

Easy-Tune Dual Brake Disc Setup

Controlled braking ability is provided by
the front and rear, individually adjustable brakes. Constructed of
thick fibre and drilled for low rotating mass and extra cooling
ability, the brakes are extremely powerful without being too
'grabby'. They're also extremely easy to tune because of the
accessible linkage.

Built to Last - Without E-Clips!

The suspension mounts front and rear are
machined from sturdy aluminium and anodized to match the chassis
and steering plate. A steel screw and washer hold the suspension
hinge pins firmly in place so you don't have to worry about them
falling out on the track.

HPI makes it as easy as possible to get into
RC off-road action. The D8S is completely pre-built and ready to go
right out of the box! Everything is assembled and tuned for you by
professionals - diffs, shocks, suspension and more are perfect
before you even open the package. HPI Ready-To-Run vehicles bring
you the same high performance and quality that you'd expect from a
high end RC kit but with the added convenience of being factory
pre-assembled to the highest standards - giving you a high
performance RC buggy straight from the box!

Just like all HPI cars and trucks, you get a full, in-depth
instruction manual with step-by-step instructions that allow you to
easily disassemble and reassemble your car for maintenance and easy
servicing. The manual also includes a handy parts list and
full-scale drawings of the parts and hardware.
